Its under side is made to serve as a platen, against which the type are carried to produce an imprint theref rom upon an interposed piece of paper.

The bar is made of the same width as the carriage, and the teeth of the rack on its upper face are made about one-half as wide, so as to leave on either side thereof a plain bearingsurface for two friction -rollers 15 15, mounted upon a stud 16, projecting from the front plate of the casing inwardly over the rack, as shown in Fig. 6. These friction-rollers serve to steady the carriage as it moves back and forth under them and to resist the pressure of the type when forced upward against the under side of the raclz-bar. The rack is made to engage a spur-wheel17,gearing with a pinion 18, fixed upon a spindle 19, mounted in the upper part of the maehine, and which carries upon its inner end a large indieating disk or wheel 20, made to project peripherally above the top of the machine, so that its face shall be brought to Viewthereat. Each face of the disk is marked with characters or numerals corresponding to these on the type, and these characters are exposed singly to view through an Opening in each plate of the cov r 21, fitted over the disk, as shown in Figs. 1 and The gear is so proportioned as that a complete movement of the type carriage (3 in either direction shall produce a complete revolution of the indicating-disk 20,'and so arranged as that the number thereon brought to view upon said dislc above the top of the machine at front and rear through the openings in the cover 21 shall correspond with that of the index-scale '12 to which the indexpointer 10 may be moved and with the particular type B brought by such movement to the line of print in the machine, as hereinafter described.

The printing from the type is eifected immediately under the friction-wheels 15 15, a strip of paper P (see Fig. (5) being fed at this point transversely through the extended slot 11 under the rack-bar 13 over the face of the particular type B which may by the movement of the type-earriage C be brought beneath it. l`he paper P is drawn from a reel R, mounted in the machine at the rear, and is fed internittently forward by means of a pair of feed-rollers 23 23, (see Fig. 2,) which are geared together by spur-wheels 21 (see Fig. 3) at one end of their axial spindles 25. Their intermittent revolution is produced by means of a cam 26 upon a crank-shaft E at one end of the machine, said cam 26 being made to revolve between two rollers (L a, fitted upon stud-pins projecting from the face of a vertically-sliding slotted bar 27, enbracing said shaft, and whose lower end is pivoted to one end of a pivoted lever 28, which engages, by neans of a forl; 2!) at its opposite end, a pin upon a vertically-sliding rack-bar 30, whose teeth mesh with a pinion 31, which re- Volves loosely upon the spindle of one of the feed-rollers and carries a pawl 33, engaging a ratchet-wheel KV, fixed to said spindle, (see Figs. 2, 3, and 0,) whereby the oscillation of the pinion, produced. by the reciprocation of the rack-bar 30, is made to produce in the customary manner an internittent rotation of the spindle.

It is evident that a stationary platen may be mounted at line of print to support the paper as it receives the impression from the type instead of the extended bar 13, and the spur-wheel1'7 be made to engage a rack on the side of the carriage.

An inking-ribbon 34, wound upon spools 35 35, mounted one at each end of the carriage C, is led longitudinally under the platen or bottom side of the rack-bar 13, its tension being secured by the frietion of the spools in their bearings.

Eaeh type B, when brought by a 'movement of the carriage Cinto position orline forprint immediately under the frietion-wheels 15, is forced up against the paper to produce an imprint thereon of the inking-ribbon 34 by the action of a type-lifter, shown in the form of an oseillating lever 36, pivoted between lugs Z) l), dependent from the side platesof the pedestal D` upon which the carriage C slides. One end of said lever 36 terminates in a finger e, turned upward immediately under the axis of the frietien-rollers 15 in line to bear against the lower end of the particular type which may be brought into line therewith. The opposite end of said lever extends to a point immediately below the crankshaft E and is pivoted to an upright bar 37, slotted to embrace the shaft E and fitted with frietion-rollers f f upon its face to embrace between then a cam 38 (see Fig. 4) upon said shaft,whereby at each revolution of the shaft and cam the lever is oscillated in manner to bear the type engaged by the lever upward against the paper at line of print.

Instead of using an inking-ribbon to obtain an impression from the type, a die-plate may be inserted upon the under side of the raek 13, having a counterpart intaglio for the opposed type snnlen in its face, so that by closing the type against the die the intervening paper shall be embossed with the appropriate character, or a strip of rubber or other elastic yielding material may be used instead of the die-plate to acconplisl the same result.

The dropping of the uplifted type to clear it from the paper when the finger end e of the lever 36 descends is enforced by means of a spring 30, (see Figs. 4 and 9,) made fast at. one end to the front plate A', so as to project with its free end in position to bear down upon the transverse pin of each type when the type is brought to line of print. As the type is noved up it carries the spring with it, so that the stress of the spring will operate to return the type so soon as it is left free.

After the paper has been imprinted and IOO IIO

fed forward for a new impression, the printed end is Severed from the strip by means of a knife 40, (see Figs. G and 7,) pivoted upon one side of the line of print against the inner face of the front plate A' between it and a parallel guard or guide plate 41, secured to the front plate upon an intervening strip placed along its lower edge, so that the knife shall be free to oscillate between the two plates and to swing upward with a drawing cut across an Opening 43, formed in the front plate A' in register with the paper strip P and in position to allow the strip as it is fed forward to pass out through said Opening 43. The upward movement of the knife 40 is produced after the paper has been moved by neans of an oscillating lever 44, (see Fig. 7,) whose forward arm is coupled to the free end of the knife by a link 45, and whose opposite end is pivoted to a slotted upright 46, embracing the crank-shaft E, and having two friction-rollers g g pivoted upon its face to enbrace between them the periphery of a cam 47, fixed upon the shaft, whereby the knife will be carried up and down at each revolution of the shaft, and in its upward novement will sever for use as a check the printed end of the strip P as it projects from the front of the casing.

The particular amount printed npon each check which is severed, as described, from the strip of paper P is added to the sum of the amounts previously printed by the m ovenent of a train of adding-wheels H, (see Fig. 6,) which naybe of any approved description, and whose construction need not herein be described. This train of adding-wheels is fitted within the casing, preferably near the top thereof, in position to be read through a suitable Opening in the casing. To actuate said wleels, a toothed wheel 50 is fixed upon the spindle of the spur-wheel 17, which gears with the rack 13 of the type-carriage C, and a horizontally-slidin g adjusting-plate 51 is inounted above the wheel 50 to reciprocate longitudinally in a direction at right angles to said spindle. This adjusting-plate 51 is provided with a rack h to engage the teeth of the wheel 50, so that the revolution of said wheel, produced by a movement of the carriage C, will operate to move said plate 51 back or forth, as the case may be. Two stud-pins 52 52 are secured to the inner face of the adj usting-plate to pass into an extended irregular longitudinal slot 53, (see Fig. 5,) cut in a guard-plate 54, (see Figs. 3 and 5,) nounted parallel with the adjusting plate and left free to slide back and forth independently thereof, yet in contact therewith, upon the stud-pins 52 52. A

third parallel'plate or addin g-slide 55, of equ al l length with the adjusting-plate 51, (see Fig. 5,) is united with the guard-plate 54 by means of lateral stud-pins 56 56, made fast to the slide to project into slots z' e', cut transversely in the guard-plate near to each end thereof. A rack la is formed centrally upon the upper edge of this adding-slide, with teetl corresponding in number and size with those of the rack h upon the lower edge of the adjusting-plate 51. The guard-plate 54 is made so much narrower than the two outer plates or slides 51 and 55 as that its edges will not overlap the racks h and k thereon when it is in a central position between said racks. It is, however, left free to move upwardly, so as to cover the teeth of the rack la on the adding-slide by reason of the vertical slots *i 2'. The longitudinal slot 53 or guideway in the guard-plate is forned in three sections m n o (see Figs. 3, 4, 8 and 9) of equal length, extending in three parallel planes, each removed from the other by a distance equal to the depth of the teeth in the rack k of the adding-slide, the two ends of the central section n, being connected the one with the end of the section m above it and the other 'with the end of the section o below it by an inclined oft'set, so that the three Sections form unitedly the one continuous irregular slot or guideway 53.

The edges of the slot form in eflect bearing-surfaces for the stud-pins 52, and it is evident that flanges or strips projecting laterally from the guard-plate may be substituted as an equivalent for the slot in providing such extended bearing-surfaces.

It will be noted that the adjusting-plate 51, which nioves in unison' with the type-carriage C, has only a longitudinal novement, that the central guard-plate 54 has both a longitudinal and an up-and-down movement against the adjusting-plate 51, and that the addingslide 55 has only a longitudinal movement.

The stud-pins 52 52, projectinginto the slot 53, are placed at a distance *apart equal to the distance between the offsets in the slots, and by reason thereof, when the guard-plate 54 is moved longitudinally over the face of the adj usting-plate 51, the former will be elevated or depressed with reference to the latr ter by means of said ofi'sets. hen thus raised, the upper edge of the guard-plate will be brought flush with the outer ends of the teeth in the rack of the adding-slide 55, so as to guard them, and when depressed it will drop to the level of the inner ends of said teeth, so as to expose them. The moment at which the guard-plate 54 will, in the longitudinal movement of the adding-slide 55, be elevated to cover the teeth of its rack 7: is deterrnined by the position of the adjustingplate 51, carrying the stud-pins 52 52, on which said guard-plate moves, said position being deternined mediately, as described, by that of the type-carriage C and of the indexpointer 6.

The adding-slide 55 is made to move back and forth a distance equal to the length of its rack 79 at each revolution of the crankshaft E by means of a crank (50 upon said shaft, (see Fig. 3,) coupled by a connecting-rod 61 with one arm of a rock-shaft 02, having a second corresponding arn 03, whose free end is forked to enbrace aprojecting pin (34 upon IOO IIO

the end of the slide 55, as is fully shown in Figs. 2, 3, and 4.

The master-Wheel 66 of the adding-train H is pivoted upon the free end of an arm 58, extending radially from one end of a rocking sleeve 59, (see Figs. 2 and 6,) oscillating upon a shaft serving as the axis for a transmittingpinion 67, gearing both with the master-Wheel and with the units-wheel of the adding-train. The opposite end of the sleeve 59 is fitted with a second longer arn (38, extending radially at a right anglc with the ar 58, the two arms forning in effectwith the internediate sleeve 59 abent lever. (See Fig. 7, 8, and 9.) The axial shaft for the rocking sleeve 59 and transnitting-pinion (37 is so located as that the master-Wheel upon the arn 58 may swing into and out of engagenent with the rack 7; of the adding-slide 55, while at the same tine it ineshcs uninterruptedly with the pinion 67. The arn 08 is actuated to produce an oscillation of the rocking sleeve 59, so as to carry the master-Wheel 66 into position to engage the rack 7; by means of a bar 09, slotted at one end (see Fig. 7) to embrace the crank-shaft E, and which is pivoted at the other to the lower end of the arm 68. A spring 70, attached to the slotted end of the Connecting-bar 69, operates automatically by its stress to swng the master-Wheel 66 into engagenent with the rack k, and the wheel is positively swung out of said position, so as to be prevented during a full halfrevolntion of the erank-shaft E from engaging the rack, by means of a cam 71 upon said shaft, whose periphery is brought to bear against a pin 72 on the connecting-bar 69, -as shown in Figs. 8 and 9 of the drawings.

An indicating-wheel is mounted on the spindle of the master-Wheel 66 to denote, in un ison with the in dicating-disk 20, the amount last added to the sum indicated on the adding-wheels H. Pawls 57 57 (see Fig. 4) are provided, as is custonary, to engage both the pinion 07 and the units-wheel of the addingtrain, so as to prevent a reverse novenent of the adding mechanism.

The several parts as described are so organized and arranged in due relation to each other as that when the index-pointer 10 is novcd to any one figure on the indeX-scale 12 the corresponding type is brought to line of print and the corresponding figure is brought to view at front and rear upon the indicating-disk 20 through the openings at the top of the machine, and simultaneously the adjusting-plate 51 is moved a distance corresponding to the relative value of the figure indicated, so as to adjust the pins 52 52, which are thereafter to guide the movement of the adding-slide 55, by neans of which the adding mechanism is actuated. Thus by means of the index-pointer 10 the type are first set and the extent of movenent of the adding mechanisn predctermined. lVhen this is accon'plished, a revolution of the crank 11, causing a rotation of the crankshaft E, will, during the first one-eighth of said revolution, allow the gear for the adding meclanisn to come into play by the movement of the can 71 on said shaft, and will simultaneously cause the adding-slide 55 to begin its movement in the direction to actuate said mechanisn. hen an eighth-revolution of the crank is accomplished, the printing-lever 36 begins to move to produce an impression from the type B, said movement being completed before a half-revolution is made. At the half-revolution the feeding mechanism begins to act to feed the imprinted slip forward outof the nachine, and the adding-slide 55, having completed its forward movement and actuated the adding mechanism, begins its return novcnent, the addinggear being first disengaged therefrom. In tle meantine, so soon as the feed of the paper is acconplished by the novcnent of the feedrollers 23 23, the knife 40 (see Fig. 7) is brought into play to cut the printed check before the revolution of the crank is fully completed.

The indeX-pointer 10 and the indicatingdisk 20 are constantly locked, so as to prevent any novement thereof, excepting only when the crank is at rest in its first or nornal position, during which the addin g mechanism is also locked. This looking of the indicating mechanism is produced by means of a star-wheel 75, fixed upon the spindle of the toothed wheel 17, which is geared to the rack 13 on the type-carriage. The Star-Wheel is engaged by a dog 76 upon one end of a lever 77, pivoted to swing upon a stud-pin S, projecting from the casing. The opposite end of the lever is provided with a pin 79 to project into a slot in one end of a reciprocating bar 80, (see Figs. 2 and 4,) slotted at its opposite end to embrace the crank-shaft E. A circular disk 81 is fitted upon said crankshaft, and a notch 82 is cut in the periphery of the disk to receive a pin 83, fitted with a friction-roller, and which projects from the face of the bar, so as to carry said roller into contact with said periphery. The notch 82 is so located as to register with the pin 83 when the crank 11 is at its nornal position of rest, (see Figs. 2, 3, and 4,) and when thus in register the lever is free to swing, so as to pernit of a disengagement of the dog 7 G from the Wheel by means of the play permitted to the pin 79 in the slot in the bar 80. So soon, however, as the crank begins to revolve the pin 83 is carried out of the notch to ridc upon the periphery of the disk 81, and the bar is thereby drawn toward the crankshaft far enough to bring the outer end of the slot through which the pin 7 9 projects into contact with said pin, and thereby prevent a movement of the dog 70 during the entire revolution of the crank.

The adding mechanismis positively locked by means of a pin 85, projectng from the casing in position to engage the teeth of the IOO IIO

master-Wheel GG when the latter is swung up out of engagement with the adding-slide, as shown in Fig'. 4; or, as an equivalent device, a dog 87 may be pivoted to the onter end of the arm 58, carrying the master-Wheel in position to drop into engagement with the teeth of said Wheel, (see Fig. 8,) its engagement being prevented, however, when the wheel is swung forward to engage the adding-slide, by neans of a pin SS, fixed to the casing to project through a slot or fork in the dog in such position as to lift the dog from the Wheel when the Wheel swing's forward, as illustrated in Fig. D. r

In the operation of the machine the amount of cash paid in, and for which a check is to be issued, is first indicated by a movement of the sliding knob G, so as to bring the indexpointer 10 in line with the figures on the indcx-scale 12 denoting said amount. This movement operates to move the sliding carriage C, so as to bring` the particular type thereon corresponding with the figure indicated into line with the printing-finger e on the oscillating lever 36 and under the strip of paper P, led transversely through the slot under the toothed bar 13 and beneath the friction-rollers 15. The novement of the carriage C thus produced operates by means of the sp ur-wheel17 and intermediate gear to produce a partial revolution of the indicatingdisk 20, so as to bring to View the figure thereon corresponding' with that indicated by the pointer 10. It operates, f urthermore, by means of the pinion 50, carried with the Wheel 17, to move the plate 51, carrying the adjustingpins 52 52, into a position whereat said pins will cause the guard-plate 54: to be carried up to disengage the master-Wheel 66 of the adding-train from the teeth of the rack 7.5 of the adding-slide 55 whenever said adding-slide, carrying the guard-plate with it, has been moved far enough to carry a number of teeth in its rack corresponding with the amount indicated by the indeX-pointer forward under the master-Wheel. By this means, when the master-Wheel has been turned by the movement of the adding-slide a number of points corresponding to the amount indicated by the pointer, the elevation of the guard-plate disengages it from the adding'-slide, and the latter will complete its movement without further actuating` the addin g mechanism. If the pointer be placed at zero, the guard-plate will prevent altogether the engagement of the master-Wheel with .the adding-slide. If the pointer be at 100, the master-Wheel will remain in engagement with the adding-slide during its full forward stroke. These movements areillustrated in Figs. 3, 4, 8, and 9 of the drawings.

In Fig. the carriage and the addin g-slide are both shown in their first or normal positions, with the pointer at zero and the zero type at line of print, the adjusting-plate being consequently likewise in its first or normal position.

In Fig'. 4 the type-carriage is represented as in the extreme position,to which it is carried when the index-pointer is at 100 and the type 100 consequently at line of print, the guard-plate and adding-slide being represented as ,in their normal position when at rest after the revolution of the crank is completed.

In Fig. 8 the adjusting-plate is represented as having' been noved one-half the length of its stroke by reason of the movement of the carriage to bring the type 50 to line of print, as is shown in Fig. 9. The stud-pins 52 52 are therefore in position to throw up the guard-plate 5-l when, in connection with the adding'-slide, it has made very nearly onehalf of its forward stroke by reason of a quarter-turn of the crank, as shown in Fig. 8. It will be noted that the subsequent continued novement of the adding-slide in completing the half-stroke will, by carrying the offsets in the slot 53 over the pins 52, cause the guardplate to rise and lift the teeth of the masterwheel 60 out of engagement with the rack k so soon as the particular tooth on the rack 79 corresponding with the type 50 at line of print has actuated and left it, thereby arresting the further movenent of the adding mechanism.

In Fig. 9 the crank is represented as having nade half its revolution, whereby, as thcrein illustrated, the adding-slide and the guardplate are brought to the end of the forward' stroke in readiness to nove back, the rack on the adding-slide being' guarded by the edgc of the guard-plate, which was uplifted midway its stroke by the position of the studpins 52 52 consequent, as above described, upon setting the type 50 at line of print, as shown.

In the revolution of the crank 11, after the desired type has been brought to line of print by a movement of the index-slide, its first movement operates to release the can 71 on the crank-shaft from the pin 7 2,"so as to allow the spring 70 to draw back the bar 69, and thereby unlock the adding mechanism and ,cause the master-Wheel 66 of the adding-train to drop into engagement with the addingslide 55. In the meantime and until the crank has completed its revolution the dog 76 will hold the star-wheel and the pinion 17 and prevent any movement thereof or of the in- IOO IIO

IZO

dicating-whcel or adjusting-slide geared thereto. Simultaneously with the release of the addiug mechanisn the adding-slide 55 will be started forward by the movement of the crank-arm 60; but as said arm is in starting upon the dead-center, as shown in Fig. 3, suificient time is permitted for the release and descent of the master-Wheel to'engage the slide before the forward movement or' the slide begins. When the crank has made a half-revolution,the movement of the addingslide is reversed, and simultaneously the master-Wheel 66 is uplifted and the adding mechanisin locked by the engagement of the master-wheel with the pin 85, (or the dog 87, as described.) In the meantime when the crank has made one-eighth of its revolution the movement of the type for inprint on the paper begins, by reason of the action of the cam 81 on the crank-shatt, and the printing is eti'eeted before the half-revointion is eompleted. At the haif-revolution the feed-rollers 23 are actuated by the operation of the ean 96 on the erank-shaft, so as to move the paper strip P forward a distance equai to the length required in the cheeks, and thereby carry the printed end of the strip out of the inaehine through the opening 4: 3. So soon as the feed ceases the knife 40 is brought into play by the cam 71 on the erank-shaft to sever the check or projeeting printed end of the strip.
